It’s popular since it provides the only way to deliver advanced streaming to iOS devices. Android and iOS devices don’t have RTSP compatible players out of the box, making this another protocol that’s rarely used for playback. The video will attempt to continue playing as much as possible. and supports resolutions up to 4K. HLS has supported MPEG TS chunks since it was released and is sometimes the only supported packaging on older HLS players. Note Unified Packager automatically sets the correct HLS protocol version for the Master and Media Playlists, based on the functionality used in each playlist. Audio output is AAC, MPEG-1 Layer II, optional MP3, and/or optional "SurCode for Dolby Digital" AC-3. This protocol structures how devices using the internet communicate. Streams are described using M3U8 playlists that are created by the HTTP server. Rather than deliver a video file in one go, HLS splits it into much smaller segments. Protocols like Secure Reliable Transport (SRT) often use UDP, whereas HTTP-based protocols use TCP. Each segment is usually 10 seconds in duration and has the extension .ts. To enable the HLS packaging mode with Transport Streams (TS), the first option on the command-line must be --package-hls. Adobe HDS (HTTP Dynamic Streaming… Basically, with DASH you get an open-source option. Streaming protocols like Real-Time Messaging Protocol (RTMP) enable speedy video delivery using dedicated streaming servers, whereas HTTP-based protocols rely on regular web servers to optimize the viewing experience and quickly scale. Hello, I’m using startMediaCasterStream() to dynamically connect to a set of streams that are then re-streamed with HLS. This directive is required for HLS or MPEG-DASH generation. RTMP MPEG-TS Pull. The lowest layer acts as a foundation, and each additional layer adds complexity. MPEG-DASH vs HLS vs RSTP . MPEG2TS playback. Although … Online video delivery uses both streaming protocols and HTTP-based protocols. HDS was developed for use with Flash Player applications as the first adaptive bitrate protocol. HLS uses an MPEG2-TS transport stream container with a configurable media segment duration, as well as a configurable playlist size for reassembling the media segments at the ingestion server. Its keyframe interval, packet size, and playback buffer requirement simply aren’t suitable for super-rapid live streaming. This is Apple HTTP Live Streaming JavaScript player created by performing realtime conversion of MPEG-TS video chunks to MPEG-4 in separate thread using Web Worker and playing them in order in main thread. to know more about HLS & MPEG-DASH, go through our blog on HLS vs MPEG DASH: Which Streaming Protocol Should You Choose? – amyst Aug 27 at 5:10 Glad, if I could help :), Well, the MPEG Transport Stream may work the same as .mp4 . As the name implies, it is the media streaming communications protocol based on HTTP; developed by Apple as part of their QuickTime, Safari, macOS, and iOS products. Unit can also redirect copies of outbound streams to multiple locations without extra CPU overhead. You can do your first HLS live stream today with the Dacast. Hot Network Questions Transfer Switch using a column that references an object_id in your own table If a scientist were to compare the blood of a human and a vampire, what would be the difference (if any)? WebRTC is a combination of standards, protocols, and JavaScript APIs that enables real-time communications (RTC, hence its name). This method measures the internet speed available to each viewer of a given video. HTTP Live Streaming (HLS) HTTP Live Streaming is known as HLS. HLS and MPEG-DASH: Which Streaming Protocol offers Better Streaming Quality? Video streaming via HLS works by chopping a MP4 video stream into short, ~ 10 second video chunks. These platforms offer integrated low latency solutions, and those are the ones to consider. But with the decline of Flash, internet video is in a transition period. September 9, 2020, 8:10pm #1. This solution lowers latency to the range of 10 seconds or less. Some of the most common HTTP-based protocols include MPEG-DASH and Apple’s HLS. The system will perform comprehensive real-time analysis on the MPEG TS in all HLS sessions, including: MPEG standard compliance based on DVB test guideline TR 101 290 A email has been sent to your email address. It does have one disadvantage, which we mention above–HLS has a relatively higher latency than some other protocols. MPEG transport stream (transport stream, MPEG-TS, MTS or TS) is a standard digital container format for transmission and Recorded in OBS using Custom FFMPEG HLS. The Common Media Application Format, or CMAF, is in itself is a media format. Mid 2019, Apple announced an extension to their HLS protocol designed to drive latency down at scale. Because HLS uses TCP-based technology, the network packet loss and recovery method is intensive. This is so, because the standard of HLS uses a “.m3u8” list instead of a “.ts” list. Over the past few years, HLS has become a standard protocol for web video, and with good reason. Last but not least, new technologies like WOWZ, WebRTC, and SRT were designed with latency in mind. This means MPEG TS typically requires 5-25 percent more … Same easy to use interface and robust Nimble Streamer behavior. Wowza Streaming Engine. Also, thumbnails can be generated for output streams on-the-fly. That is one of the reasons for the increased latency. This playlist also called a manifest file, indexes the video chunks. HTTP Live Streaming sink/server. HLS. SCTE-35 markers passthrough is supported for MPEG-TS and HLS. Same easy to use interface and robust Nimble Streamer behavior. MPEG2-TS continues to play an important role in ABR streaming through its adoption as the encapsulation format for segments in ABR streaming standards such as Apple HTTP Live Streaming (HLS). RTSP/RTP is even quicker at around two seconds. SCTE-35 markers from MPEG-TS stream can be used for Nimble Advertizer ads insertion. The protocols used for streaming sit on top of these. This is why Nimble Streamer had support for transmuxing MPEG-TS into HLS streams for a long time. MPEG TS typically has a 5-25 percent packaging overhead. would the stream … These are contained within a MPEG-2 transport stream. In theory it isn’t possible to say which protocol is better for live streaming as it largely depends on your project and the devices which you plan to distribute a live stream to. HLS has supported MPEG TS chunks since it was released and is sometimes the only supported packaging on older HLS players. This is the reason why standardization is so important. stream to a set-top box or HW decoder to convert live video from Axis IP camera to HD-SDI, SD-SDI, HDMI or DVI. MPEG TS typically has a 5-25 percent packaging overhead. Apple HLS (HTTP Live Streaming) Low-Latency HLS. HLS is an adaptive bitrate live streaming video protocol. Required fields are marked *. HLS uses a method called Adaptive Bitrate Streaming. The Moving Pictures Expert Group (MPEG), an international authority on digital audio and video standards, developed Dynamic Adaptive Streaming over HTTP (DASH) as an industry-standard alternative to HLS. --hls.optimized¶ Output MPEG-TS streams with optimized PES placement. First of all let define, “Media Streaming”, “Streaming Protocol” and “Latency”: Media streaming is the transfer of media data from source to target. That’s why we’re especially excited to see low-latency CMAF for DASH and Low-Latency HLS take off. But you may be looking to deploy a one-to-few conference, in which case WebRTC would be better suited. This article is going to take a look at the pros and cons of HTTP Live Streaming. As of 2019, an annual video industry survey has consistently found it to be the most popular streaming format. HLS was developed to provide an alternative to Flash video. HLS is a wrapper that connects to multiple streams of varying quality, so it can stream better without buffering. MPEG-DASH is codec and resolution agnostic, which means MPEG-DASH can stream video and audio of any format (H.264, H.265, AAC, etc.) HLS is h264-compressed video with aac- or mp3-compressed audio, transported with MPEG-TS. Hello, I’m using startMediaCasterStream() to dynamically connect to a set of streams that are then re-streamed with HLS. 783 views Most often, these segments are between 2 and 10 seconds long, and packaged in the MPEG-TS format, though fragmented MP4 is supported in newer versions of the HLS spec. More importantly, a stream delivered via HLS will play back on the majority of devices — thereby expanding your audience. You can think of the streaming protocol as the method that defines what format the video uses, how it’s compressed, the size of the chunks sent, and so on. The last URI component is used as a stream name. So you can e.g. A playlist containing an MPEG-2 transport stream can also apply the #EXT-X-MAP tag, but each segment typically includes the information required to parse it so it’s not needed. That way, protocols at each layer can focus on a specific function and cooperate with each other. The system will perform comprehensive real-time analysis on the MPEG TS in all HLS sessions, including: MPEG standard compliance based on DVB test guideline TR 101 290 DASH and RTSP are fully codec agnostic, meaning they are capable of wrapping around any type of video codec. These protocols achieve this by transmitting the data using a firehose approach rather than requiring local download or caching. For almost all viewers, a high-quality video that is watchable anytime, on any device, is more important than latency. Benefits of MPEG-DASH DASH is codec agnostic and supports almost every video codec available including H.264, H.265/HEVC, VP9/10 and WebM Supports all kinds of audio codecs including AAC and MP3 Like HLS, MPEG … This media can be a file or a live data captured by the camera at the moment. It is the most up-to-date and widely used protocol for media streaming. I want to stream the MPEG-PS/TS file directly from Streambaby while its concurrently downloading the file from my philly Roamio+. There’s no need to use a specific device to watch the content. HLS test streams (.m3u8 streams) are a little harder to come by due to the nature of the technology. All rights reserved. Each time you watch a live stream or video on demand, streaming protocols are used to deliver data over the internet. Video streaming via HLS works by chopping an MP4 video stream into short, ~10-second video chunks. Any questions about HLS? HLS is overall quite plain but complex, so it behaves differently on different devices. The mobile device will pull the stream from the Wowza server using the RTSP/RTP protocol. MPEG-DASH (Moving Picture Expert Group Dynamic Adaptive Streaming over HTTP) Low-Latency CMAF for DASH (Common Media Application Format for DASH) Microsoft Smooth Streaming. It breaks the overall stream into a sequence of small HTTP-based transport stream (.ts) files. According to Google, “with Chrome, Edge, Firefox, and Safari supporting WebRTC, more than 85% of all installed browsers globally have become a client for real-time communications on the internet.”. Those two HLS last parts, both point to the same m3u list, that is composed of m3u8 links. The stream is divided into chunks described in m3u8 playlists and is transmitted over HTTP. HTTP Live Streaming (also known as HLS) is an HTTP-based adaptive bitrate streaming communications protocol developed by Apple Inc. and released in 2009. Technically speaking,HLS uses h. 264 video compression,AAC or MP3 for audio compression, and transmit streams using the MPEG TS container format. So to clear this up first of all, these are “containers” that wrap around the actual video, which is a particular “codec” (such as h264). Let’s take a look at one of the most prevalent issues: latency. Otherwise, MPEG-DASH functions much the same as HLS. The Unified Origin supports backward compatibility by trans-multiplexing fragmented MP4 to MPEG-2 TS on the fly. The other difference is the file extension of the segments is .m4s instead of .ts. The writing on the wall came when Adobe announced the death of Flash — slated for 2020. Here at Dacast, we’re offering a low-latency HLS streaming solution for our Premium plans and above. Streams deployed over HTTP are not technically “streams.” Rather, they’re progressive downloads sent via regular web servers. Pick MPEGTS with the ending part “output=ts”, or pick HLS with the ending part of either “output=m3u8”, or “output=hls”. For example, if the URI is /foo/bar/baz, the stream name is baz. Thanks for tuning in, and good luck with your live streams! This open-source protocol is recognized as a proven alternative to proprietary transport technologies — helping to deliver reliable streams, regardless of network quality. Despite these disadvantages it is ideal to use RTMP as a transport stream, it can be transcoded into other formats such as HLS which can be distributed more easily. MPEG2-TS is one of the most popular streaming protocols used by various types of businesses. The module provides HLS and MPEG-DASH live streaming capabilities for those who want a lightweight solution based on the HTTP protocol. So your Nimble Steamer will be working as a streaming origin. Technically speaking, HLS uses h.264 video compression, AAC, or MP3 for audio compression, and transmits streams using the MPEG-TS container format. to know more about HLS & MPEG-DASH, go through our blog on HLS vs MPEG DASH: Which Streaming Protocol Should You Choose? Initially, MPEG-DASH held the advantage due to its codec agnostic characteristic. The ABR HLS streams definition is similar to producing ABR HLS from RTMP. TS is a straight stream, you get what you get. The initiator (client) asks the accepter (server) to start a connection, the accepter responds, and the initiator acknowledges the response and maintains a session between either end. MSE decodes the data and provides the video object to the player to stream. Unlike the old hlssink which took a muxed MPEG-TS stream as input, this element takes elementary audio and video streams as input and handles the muxing internally. Even more, if the video file type is in an mp4 format, you can record videos directly using the unique video capture function. MPEG-2 TS Segments MPEG-DASH and Apple HLS can use MPEG-2 TS format segments that have a significant higher overhead than ISO Base Media File Format based segments. These are layered on top of one another to form a protocol stack. It often mistakenly gets defined as HTML5 streaming, but is not part of HTML5. The final benefit of HLS that we’ll highlight here is security. We’d love to hear from you in the comments below, and we will get back to you. HLS is short for HTTP Live Streaming.It is a protocol used to stream live video over the internet. Any questions about HLS? Its fragments must use the MPEG-2 Transport Stream (MPEG2-TS, M2TS or TS) container format, so there … Hi folks, I need to pull streams from one Nimble server to another (between countries, with less-than-reliable internet connectivity). H264 has to be used as the video codec. RTMP encoders are still a go-to for many content producers even though the proprietary protocol has fallen out of favor for last-mile delivery. Unified Streaming Platform can be used to standardize on CMAF. What is the difference between old Winamp-m3u-playlists and the hls format? However, each protocol obviously has its own pros and cons. Therefore, they overhead caused by these headers increases proportionally with the segment size, which means that … Microsoft developed Microsoft Smooth Streaming for use with Silverlight player applications. The stream is published in the MPEG-TS format over HTTP. And for exclusive offers and regular live streaming tips, you’re also invited to join our LinkedIn group. So your Nimble Steamer will be working as a streaming origin. RTSP support is still ubiquitous in IP cameras. Along with the adoption of ABR streaming, there has been a significant focus on video compression efficiencies to provide users with a better experience over constrained and varying … But open standards and adaptive bitrate streaming eventually edged RTMP out. Even a dedicated home or work internet connection can have a significant variation in internet speeds. Fragmented MP4 is supported. For this reason, HLS remains the de facto standard. To learn more, check out our article on the update. This approach leads to a superior user experience. Because HLS uses a series of short chunks of an MPEG transport stream to deliver the video data, the underlying stream must be compliant with the MPEG standards. HLS was developed to provide an alternative to Flash video. Downloaded audio and video data is converted to mp4 as it is with the same quality without re-encoding. MPEG-DASH vs HLS vs RSTP . Replacements for HLS are in the works (such as fragmented MP4), but devices aren’t yet ready to play them. You may also pass through areas of limited bandwidth availability. © 2005–2020 Wowza Media Systems, LLC. Hopefully, this article has educated you on the basics of this technology, how it works, and what its upsides and downsides are. Let’s take a look at some of the pros of using the HLMS protocol for video streaming. There are a few cons to using HLS. re-packages) streams from either of sources into: HLS; RTMP; MPEG-DASH; Icecast; MPEG2TS playback; … However, each protocol obviously has its own pros and cons. adaptive bitrate live streaming video protocol, HLS simply provides a more secure browser, Streaming Protocols for Live Broadcasting: Everything You Need to Know in 2020, Top 10 Live Streaming Platforms: Everything You Need to Know [2020 Update], 5 Virtual Christmas Program Ideas for Church Services – 2020 Holiday Season, Streaming Server Pricing: The Cost of Live Streaming An Event [2021 Update], How to Improve Live Streaming Quality in 8 Steps [2021 Update], Your Guide to the Best Live Streaming Equipment [2020 Update]. For one, the protocol supports adaptive bitrate streaming, which is key to viewer experience. This way, Unified Origin provides the same benefits as CMAF for legacy content. Instead of using a single video file, HLS separates a video into many small parts. To enable the HLS packaging mode with Transport Streams (TS), the first option on the command-line must be --package-hls. For example, you may begin watching a video at home, where you have a fast Wi-Fi connection. In these situations, speed is important. The majority of Apple devices rely on older HLS versions based on MPEG-2 TS. This is Apple HTTP Live Streaming JavaScript player created by performing realtime conversion of MPEG-TS video chunks to MPEG-4 in separate thread using Web Worker and playing them in order in main thread. 1. Your email address will not be published. It is a format developed by Apple. Each stream is encoded with Medium Profile H.264 at .1 to 15 Mbps. Note Unified Packager automatically sets the correct HLS protocol version for the Master and Media Playlists, based on the functionality used in each playlist. HLS Playback Start Time: RTSP vs MPEG-TS source stream. A simple way to stream MPEG-TS over HTTP is by running ffmpeg: UDP, on the other hand, starts without requiring any handshake. RTMP vs HLS. Therefore, it usually adds a delay of 20-60 seconds to your stream. share | improve this question | follow | asked Nov 1 '19 at 7:41. theva theva. The two iconic technologies used to provide Adaptive HTTP Streaming … These work best for streaming to a small audience from a dedicated media server. As we’ve said, the format is supported by just about every device via HTML5 and Media Source Extensions. This internet may be slower. That next shift may still be a few years out. MPEG-2 TS consists of packets with 188 bytes in size, where each packet has headers with a varying size of 4 to 12 bytes. DASH and RTSP are fully codec agnostic, meaning they are capable of wrapping around any type of video codec. This usually is only a problem for a small subset of live streamers—notably, video gamers and sports fans. Next The 3 mentioned steps allow processing any multicast or unicast UDP MPEG-TS stream into HLS adaptive bitrate stream. It transmuxes (i.e. Launching Visual Studio. No credit card required. By prioritizing the above considerations, it’s easy to narrow down what’s best for you. Although it’s quickly taking the industry by storm, SRT is most often used for first-mile contribution rather than last-mile delivery. Mid 2019, Apple announced an extension to their HLS protocol designed to drive latency down at scale. HLS supports multi-bitrate streams, Live/VOD. The stream is transported using UDP. Traditional streaming protocols, such as RTSP and RTMP, support low-latency streaming. HLS is pretty simple to set up, it’s free to use, and it’s supported on a wide range of devices. What’s more, content distributors don’t always stick with the same protocol from capture to playback. MPEG-DASH and Apple HLS can use MPEG-2 TS format segments that have a significant higher overhead than ISO Base Media File Format based segments. From recovering lost packets to preserving timing behavior, SRT was designed to solve the challenges of video contribution and distribution across the public internet. While RTSP is a presentation-layer protocol that lets end users command media servers via pause and play capabilities, RTP is a transport protocol used to move said data. 1111. Learn more about how this works here. Initially, MPEG-DASH held the advantage due to its codec agnostic characteristic. Comment document.getElementById("comment").setAttribute( "id", "a44dbbf40dc1c9682f675b7f833968c3" );document.getElementById("g43d89dd58").setAttribute( "id", "comment" ); Sign Up For A Free 30-day Trial To Make Your Video Streaming Unforgettable. However, several key differences distinguish the two protocols: It enables adaptive delivery to all Microsoft devices. Her background is in streaming and content delivery. This means MPEG TS typically requires 5-25 percent more bandwidth and cost than fMP4. HLS uses an MPEG2-TS transport stream container with a configurable media segment duration, as well as a configurable playlist size for reassembling the media segments at the ingestion server. Nimble Streamer allows playing live streams via HTTP MPEG2TS. A majority of web browsers also support the leading alternative—MPEG-DASH—but iOS and Safari don’t. Nimble is able to take MPEG2TS incoming stream via both UDP and HTTP. We recommend adopting the HLS streaming protocol all of the time. Intra-server pull: RTMP vs MPEG-TS more reliable? These include HTTP Live Streaming (HLS) and MPEG-DASH. The maximum limits for active HLS and MPEG-DASH streaming sessions are independent of each other. Similar to low-latency CMAF for DASH and Apple Low-Latency HLS, these protocols continue to evolve. After the stream you can merge all the segments into a single file simply by concatenating them in order. 4,196 9 9 gold badges 34 34 silver badges 69 69 bronze badges. Both protocols run over HTTP, use TCP as their transport protocol, break video into segments with an accompanying index file, and offer adaptive bitrate streaming. Originally developed by Apple for use on iOS, Mac OS, and Apple TV devices, HLS streaming has become the most widely used live video protocol. First, HTTP Live Streaming supports video on just about every device. The other difference is the file extension of the segments is .m4s instead of .ts. The reason is simple. Another major advantage of HLS is its lower cost. When comparing the streaming quality between MPEG-DASH vs. HLS, the answer is that both are at par and there is not much difference between the two rival protocols. Compared to Flash, HLS simply provides a more secure browser for your viewers—both when they’re watching your content, as well as afterward. ), Use (first-mile contribution vs. last-mile delivery). can I use .mp4 in HLS streaming? Optimized PES placement reduces the overhead introduced by the MPEG-TS container, especially for low bitrate video streams. Whether you and your viewers are accessing content on a smartphone, tablet, desktop or laptop, smart TV, set-top box, or any other device, HLS video will play. You can do your first HLS live stream today with the Dacast video streaming solution. You can set it up using this scenario along with other output protocols. HLS (Http Live Streaming) vs MPEG DASH. The industry of adaptive HTTP streaming technologies is currently led by Apple with HTTP Live Streaming (HLS) and the internationally standardized Dynamic Adaptive Streaming over HTTP from MPEG, MPEG-DASH. Quality will scale up as long as your internet is fast enough to handle the load. 0. mpeg-dash and codecs specification. Is the .ts files still in the same content type as the mp3? (Defaults to false.) With the Stream Recorder, you can easily save live and archived videos that are delivered in a typical HLS (m3u8) format. Support for the protocol is widespread in media players, web browsers, mobile devices, and streaming media servers. HLS is a streaming protocol that was developed by Apple. While Flash’s end-of-life date is overdue, the same cannot be said for using RTMP for video contribution. However, most users can easily ignore the small latency of an HLS stream as it will have no impact on viewer satisfaction or experience. When it comes to MPEG-DASH, the acronym spells out the story. When comparing the streaming quality between MPEG-DASH vs. HLS, the answer is that both are at par and there is not much difference between the two rival protocols. That’s a major advantage. HLS was designed to maximize quality, not to minimize absolute latency. It is not an open standard like MPEG-DASH and so it does not have as … HLS is h264-compressed video with aac- or mp3-compressed audio, transported with MPEG-TS. Originally developed by Apple, the purpose of HLS was to make the iPhone capable of accessing live streams.. At first, HLS was exclusive to iPhones, but today almost every device supports this protocol, so it has become a proprietary format. HLS is another streaming protocol in wide use today. MPEG-DASH, Microsoft and Adobe can use ISO Base Media File Format based segments, e.g., MP4, that has a significant lower overhead than MPEG-2 TS segments used by Apple HLS. Follow…, International Organization for Standardization’s (IS0’s) Open Systems Interconnection model, Online video delivery uses both streaming protocols and HTTP-based protocols, network glitch to corrupt the data en route, Streams deployed over HTTP are not technically “streams.”, Apple announced an extension to their HLS protocol, Quality of experience (adaptive bitrate enabled, etc. I’m noticing big playback start time differences between an RTSP and an MPEG-TS source: it takes around 0.5-0.7 seconds to connect to the MPEG-TS stream and between 4-15 !! Standard web servers can handle HLS delivery with no problem (depending on load and other factors). It transports data regardless of any bandwidth constrains, making it speedier and riskier. HLS also adds more overhead. All Google Chrome browsers, as well as Android, Linux, Microsoft, and MacOS devices can play streams delivered using HLS. Your email address will not be published. For example, a stream sent in HLS won’t work if the receiver’s device doesn´t support this format. Streams are described using M3U8 playlists that are created by the HTTP server. HLS stands for HTTP Live Streaming and is Apple’s proprietary streaming format based on MPEG2-TS. How does it work? For this reason, TCP is quite reliable and can solve for packet loss and ordering. The ABR HLS streams definition is similar to producing ABR HLS from RTMP. Video streaming via HLS works by chopping an MP4 video stream into short, ~10-second video chunks. Unlike standard HLS, Apple Low-Latency HLS doesn’t yet support adaptive bitrate streaming — but it is on the roadmap. As shown above, RTMP delivers video at roughly the same pace as a cable broadcast — in just over five seconds. Next The 3 mentioned steps allow processing any multicast or unicast UDP MPEG-TS stream into HLS adaptive bitrate stream. It is a HLS segmenter which takes in an UDP/MPEG-TS stream from tsrecompressor and generates a media playlist, including the new tags above. While its transfer setup differs from that of Low-Latency HLS, the use of shorter data segments is quite similar. Flash video provided low latency live streaming. We’ll also look at the history of HLS, and ask where it came from, and why. There aren’t any fantastic solutions to the HLS latency issue yet. But when paired with chunked encoding and chunked transfer encoding for delivery over DASH, it should support sub-three-second delivery. HLS supports multi-bitrate streams, Live/VOD. Terms | Privacy | Trademarks | Legal, As a Colorado-based B2B tech writer, Traci Ruether serves as Wowza's content marketing manager. It applies to every segment that appears after it. Since Apple’s a major player in the world of internet-connected devices, it follows that Apple’s HLS protocol rules the digital video landscape. For anyone who wasn’t sure what I was talking about when listing the audio and video codecs for each protocol, this video will walk you through the difference. Recording. Nimble … This text file, specially formatted for HLS, also contains metadata about the stream. Adobe designed the RTMP specification for the transmission of audio and video data between technologies like a dedicated streaming server and the Adobe Flash Player.
